Driving home last night the truck just started to sound aweful and was losing power. At first I thought i could be out of fuel cause I was pretty low and im now sure how accurate the gauge is. So I got some fuel put it in the tank and the bowl and tried to fire it up. It will turn over and turn over but nothing. Is there something else I got to do to prime it other than fill the bowl? When it runs out of gas does it sound like absolute ####?
